TROLLEY-CAR FOR WIRE-ROPE OR SUSPENSION RAIIiWAYS.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed September 6. 1907. Serial No. 391.643-

.To all whom it may concern:

Be it known that I, RUDOLF PFAFFEN BACH, a subject of the GermanEmperor, residing at Leipzig, in the Empire of Germany, have inventedcertain new and useful Improvements in Trolley-Cars for ire-Rope orSuspension Railways, of which the following is a specification.

This invention relates to improvements in trolley cars for wire rope orsuspension railways.

The improved car has two travelers either or both of which are providedwith rope gripping devices actuated by the weight of the load. Theconnecting member of the two travelers from which the load is suspendedis not directly fixed to the body of the travelers on which grippers arefitted, but is joined to the movable gripping members of the grippers.

The invention is illustrated in the annexed drawing in which Figure 1 isa side elevation of the car traveling on a horizontal rope theconnecting member being connected at one end to the gripping device forthe hauling rope of one traveler and joined at its other end to thesecond traveler, Fig. 2 is a vertical section through the travelerprovided with the gripper. Fig. 3 is a plan of the under side of thegripper. Fig. 1 is a side elevation of a car of the same construction asFig. 1 and shows same traveling on an inclined rope. Fig. 5 is a sideelevation of a second form of construction in which the connectingmember is connected at each end to the hauling rope grippers which areprovided on both travelers.

The car has two travelers a and. b, which are connected together bymeans of the member c. The member 0 is pivotally connected at a point (Zbetween the two travelers to a frame 6 carrying the load-receiving-boxf. The one end g of the member 0 is connected by means of a universaljoint 71 to the traveler Z), (Figs. 1 and 2) so that the member 0 canhave free movement in both the vertical and horizontal planes. The otherend of the member 0, is, in order to be also able to execute bothmovements, connected in a similar manner with the body of the traveler afor example by being connected by a horizontal pivot i to the sleeve isliding and rotating upon the rod i pivoted at i to the carriage or.This end of member 0 acts preferably with the aid of levers 7c, Z (Figs.2 and 3) on the movable gripping member m of the hauling rope gripperwhich is arranged on the traveler a The hauling rope n is thus grippedwith the aid of the pressure, transferred by the carload f on thesuspension frame e and the member 0. The gripping devices may be of anyknown construction and can engage an upper or lower rope.

In the form o1 construction shown in Fig. 5 both travelers a and b areeach provided with a gripper m The member 0 connecting the two travelersis connected to the travelers a and b by means of universal joints k andgoverns by means of the intermediate connecting straps 0 the action ofthe grippers m of the hauling rope, said grippers being provided on bothtravelers.

What I claim as my invention and desire to secure by Letters Patent ofthe United States is Improved trolley car for rope or suspensionrailways comprising in combination two vehicular travelers, a supportingmember, universal joints connecting said member to the two travelers, ahauling rope gripper comprising a movable member, and connection betweenthe connecting member and movable gripper member whereby the loadcarried operates upon the movable gripping member.

In witness whereof I have signed this specification in the presence oftwo witnesses.

RUDOLF PFAFFENBACH.
